Thirty IR has been testing a number of PC titles in 8K resolution these past few months, and released some videos showcasing Crysis 3, The Witcher 3, Project CARS, Battlefield 1 and For Honor running in such a ridiculously high resolution.

Nothing ridiculous about 8K, in my opinion it's the first resolution level that starts approaching "all you need".

It's 300 PPI almost exactly on a 30-inch screen, so a human being will no longer have any chance of seeing pixelation. This will make text very smooth and pleasant to look at - and yes, also make games look great.
